MARION F. WOOTEN, OF CHARLOTTE, NORTH CAROLINA, ASSIGNOR, BY MESNE ASSIGN- TH'IENTS, TO AMERICAN AUTOMATIC SODA FOUNTAIN COMPANY, OF CHARLOTTE, NORTH CAROLINA, A CORPORATION OF NORTH CAROLINA.

SODA-WATER-DISPEN S13 G MZABATUS.

Application filed June 28, 1915.

To all whom it may concern:

Be it known that I, MARION F. Woolen, a

citizen of the United States of America, anda resident of Charlotte, county of Mecklenburg, and State of North Carolina, have in vented certain new and useful improvements in Soda- Water- Dispensing Apparatus, of which the following is a full and clear specification, reference being had to the accompanying drawing, in which Figure I. is a vertical sectional view of an apparatus embodying my invention; and

Fig. 2 is a detail view hereinafter described.

The object of this invention is to provide simple mechanism for dispensing simultaneously a measured quantity of syrup and a measured quantity of water under pressure, whereby the apparatus will deliver to the customer a drink of soda water properly mixed with the desired syrup, as more fully hereinafter set forth.

in the drawings, a designates a syrup tank and b a trap chamber connected thereto so as to fill by gravity through a passage containing a valve 0. This chamber 6 is connected by a conduit d with the interior of a discharge nozzle 6, this nozzle being arranged to discharge downwardly as usual. in the conduit (1 is a valve f.

Connected to the nozzle e is a trap chamher 9 connected by pipe h to the cooling coil i of a suitable carbonated-water tank. ingress of water under pressure to chamber 9 is controlled by valve 7', and its egress through nozzle 6 is controlled by valve k. A vertically moving rod Z is attached by a pin and slot connection to four arms m, which are respectively connected to the valves 0, f, j and is, whereby these valves are simultaneously operated by the vertical movement of the rod Z. lhe valves are so adjusted that when the rod is moved downwardly the valves 7 and it will open and the valves 9' and 0 will close.

The rod Z is raised and lowered by means ofa horizontal shaft n journaled in a casing and provided with a gear wheel 0, which wheel 0 through the medium of an interme diate idle gear 37 engages a toothed rack on the rod Z, so that by turning said shaft n (preferably by means of a crank g) to the right, the rod Z will be pushed downwardly, and by turning the shaft in the opposite di- Specifieation of Ietters Patent.

rection will be raised. Any suitable coincontrolled devices may be used in connection with my apparatus.

in the coin-controlled devices shown, a downwardly inclined coin-receiving tube 1* is provided. The coin passage to this tube is restricted by shoulder a, which is arranged coincident to the lateral passage 2 A. coin of the proper thickness will strike shoulder s and be deflected into passage 6 and thence be discharged into a coin cup u, but should the coin be thinner than the predetermined coin, it will not strike shoulder s but will remain in the main passage and be discharged at the end of the tube 7, at a point away from the cup u. I

The cup u is attachedto lever o pivotally mounted adjacent to a wheel w attached to shaft n, said lever being provided with an arm :0 which bears gravitatingly upon the periphery of wheel to and normally tends to drop into a notch y formed in the periphery of the wheel. Attached to the shaft 92 is a convolute spring .2 adapted to be tensioned when the shaft n is rotated to the right.

When the upper valves 0 and j are open, theshaft n is locked by the arm w and the spring a is without tension. With the parts 1n this position, the two trap chambers will be filled from their respective sources of supply. Upon the dropping of a coin into cup 16, the weight of the coin will be suficient to overbalance the normal and preponderating weight of the arm to and thus cause the cup end of the lever to descend. This descent is suiiicient to release the wheel 10, but is not suficient to discharge the coin, this restricted descent being dependent upon the throwing upon the shaft 12 the finger a directly under the cup. When the parts are thus released, the operator turns shaft n to the right, thus winding up spring a, closing valves 0 and j and opening valves f and is. The carbonated-water under pressure in chamber 9 will be forcibly discharged, and this forcible discharge will, by suction, assist the action of gravity in emptying the syrup chamber Z) of its charge, the water and the syrup being at the same time thoroughly mixed. Upon the complete discharge of the liquids, the operator will release the crank handle 9 and the spring a will restore the parts to normal, the rotation of the shaft n having previously permitted the
